This is an interactive homework problem for introductory physics students relating to Newton's Second Law. Inside an accelerating car, a ball of known mass hangs from a string. Given the string displacement from the vertical, the student must determine the magnitude of the car's acceleration. A user-activated "help" sequence promotes understanding of this situation relative to positions both inside and outside the car. Included are a step-by-step conceptual analysis, free-body diagrams, and explanation of math applications. Immediate feedback is received for both correct and incorrect responses.
This item is part of a larger collection of interactive homework problems for introductory physics. See Related items on this page for a link to the full collection.
